Biggest opportunity: Swap “woocommerce” and “custom css” for “optional” and “infinite scroll”. “woocommerce” isn't earning its slot: you're not in the first 24 results for its own search. “optional” sits at #21 untagged, close enough for a declared tag to move it up. “custom css” isn't earning its slot: it only gets you to #15. “infinite scroll” sits at #22 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 6K of 85.4K lifetime downloads are still running, above its category: the median eCommerce plugin keeps 1.4%, across 5,154 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other eCommerce plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 1 release in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

What to do about it
- Swap “woocommerce” and “custom css” for “optional” and “infinite scroll”. “woocommerce” isn't earning its slot: you're not in the first 24 results for its own search. “optional” sits at #21 untagged, close enough for a declared tag to move it up. “custom css” isn't earning its slot: it only gets you to #15. “infinite scroll” sits at #22 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “custom css”. #15 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

Be warned! This plugin is a sneaky scam. Out of nowhere, a giant info box shoves a payment message in your face on the WordPress admin page. It’s clear the developer has no clue about user experience, and leaving their code on your site is a recipe for disaster. This topic was modified 2 years, 2 months ago by brandoncollins.

Uninstalled. Spams the WP Admin page with money begs.

The CSS metabox has a spinner that continuously spin, and the CSS is now inject inside the BODY content of the page instead of the HEAD… probably another bug. Had to switch to Simple CSS. It inject the code in the header and minify it. This topic was modified 2 years, 5 months ago by revixi5.

The plugin is very useful

I am surprised this plugin is not more popular. It is a great way to add a little CSS to a page. Sometimes I just find it handy when I want to test CSS before adding it to my main stylesheet. Especially if I want to show someone global page changes before actually doing them globally.

Hi! Great plugin, exactly what I was looking for. On my version (6.1.1) the CSS validation fails due to line 679 (there is no data object in wp object).const ppsccEditPost = wp.data.select('core/edit-post'); Otherwise the CSS saves and displays correctly.

While it is a useful plugin, it does not wok in comments pagination. For example, you can use it to have custom CSS in a single page address: domain.com/title/ (custom css different from the general CSS of the whole site are used), but it does not work for comments pages of the same address such as: domain.com/title/comment-page1 or domain.com/title/comment-page2 As you know, there is no separate editing environment for comments pages. As a result, there is no separate box to add custom css for comments pages. Suggestion for the next update: the plugin will be more useful if the custom CSS of each single page work for all of its comments pages (from first comments page to the last one).
